Discover the unique landscape of Hon Seo Island, a small, uninhabited islet near the Phuong Mai Peninsula, accessible by boat. Unlike sandy beaches, Hon Seo is known for its fascinating rocky shores, particularly a beach composed entirely of smooth, round stones polished by the waves over millennia, creating a visually stunning natural mosaic.

The clear waters surrounding Hon Seo Island also offer good conditions for snorkelling to observe marine life among the rocks. Its wild, pristine beauty and unique geological features make it an interesting stop on an island hopping tour around Quy Nhon for those seeking natural wonders.
